    Opposition is when the planet and the Sun are opposite each other in the sky, thus forming a line planet-Earth Sun. This is not possible for an inferior planet - one close to the Sun than Earth.

    Superior conjunction is when the planet and Sun are in the same place, with the Sun nearer to Earth, thus forming a line planet-Sun-Earth. This is possible for all planets, but for superior planets it's the only sort of conjunction possible.

    Opposition and conjunctions occur when the planet and earth align with the sun.

    With all planets they can pass on the other side of the sun from the earth.

    With inferior planets they can pass directly between the sun and the earth.

    With the outer planets (superior) the earth comes between the planet and the sun. That is not possible for an inferior planet = option C

    Greatest Eastern & Western elongation is possible for all planets. It is when they reach their maximum angular distance from the sun.

    B. Superior Conjunction

    That is when the Earth is directly between the Sun and that planet, which can never happen for a planet closer to the Sun than Earth.
